Journal of International Oncology 2017;44(3):161-164
Objective To investigate the incidence and epidemiological characteristics of esophageal cancer in Kashgar region,and to provide theoretical basis for the comprehensive prevention and treatment of esophageal cancer.Methods A total of 1 815 cases of esophageal cancer were collected from January 2015 to December 2015.The morbid feature was analyzed and fitting-conditional Logistic model multivariate analysis was used to infer the influence factors.Results In 1 815 cases of esophageal cancer,the sex ratio was 2.4/1.0,and there were more men than women (x2 =5.90,P =0.015).Age of onset was mainly focused on 51-70 years old.The incidence rate of Shule County was the highest.Logistic model multivariate analysis showed that esophageal cancer was closely related to the three factors:fast food intaking speed (x2 =17.756,P < 0.001),hot eating habit (x2 =8.234,P =0.003) and history of stomach diseases (x2 =14.421,P < 0.001).Conclusion The morbidity of esophageal cancer maintains a high level in Kashgar region,which may be related to the local residents life habits,history of stomach diseases and other factors.Comprehensive strategy of prophylaxis and treatment must be taken.
2.Kv7 channels in modulation of central monoaminergic neurotransmission
Chinese Pharmacological Bulletin 2014;(10):1350-1352,1353
The KCNQ gene family encodes five Kv7 channel sub-units(Kv7. 1-5) and four of these (Kv7. 2-5) channels are ex-pressed in the central nervous system ( CNS ) . Neuronal Kv7 channels participate in both pre-and post-synaptic modulation of neurotransmissions. Activation of neuronal Kv7 channels inhibits neuronal excitability and limits the release of monoaminergic neu-rotransmitter. Kv7 channel openers provide novel therapeutic op-tions in the treatment of disease states characterized by overactiv-ity of monoaminergic neurons ( e. g. schizophrenia, anxiety and drug abuse) . This review summarizes the studies on expression and functional role of Kv7 channels in monoaminergic neurotrans-mission in the CNS and the potential therapeutic effect of Kv7 channel openers on the disease characterized by overactivity of monoaminergic neurons.

Chinese Journal of Tissue Engineering Research 2005;9(46):176-177
BACKGROUND: Simple acupuncture therapy often fails to produce significant relief of pain induced by chronic soft tissue injury, but liquid acupuncture therapy, with its longer action on the acupoint and the synergistic effect of the drugs, may, at least theoretically, have better effect.OBJECTIVE: To observe the effect of fluid acupuncture therapy with compound Danshen injection solution combined with spectrum therapy for relieving pain caused by chronic soft tissue injury.DESIGN: A case-control observationSETTING: Health Clinic, College of Engineering of Nanjing Agricultural UniversityPARTICIPANTS: Ninety-four outpatients with chronic soft tissue injury treated in the Health Clinic of College of Engineering, Nanjing Agricultural University between May 2001 and November 2004 participated in this experiment on a voluntary basis. The patients were divided into liquid acupuncture therapy combined with spectrum therapy group (Combined treatment group)and acupuncture control group, with 47 patients in each group.METHODS: In combined treatment group, the acupuncture was administered on the acupoints offengchi (GB 20), tianzong (SI11), quyuan (SI13),ashixue, beishuxue, and jiajixue. Compound Danshen injection solution was injected into each acupoint 2 to 3 cm. Two acupoints were chosen from each region of pain for injection every other day, for 30 days for a treatment course. After the injection, the sites of injection were subjected to spectrum therapy for 30 minutes every other day, for 30 days for a treatment course. One course of acupuncture and spectrum therapy was administered separately. In the acupuncture control group, the above acupoints were chosen for simple acupuncture therapy in identical treatment course.Visual anologue score (VAS) was used for evaluation of the therapeutic effects before and 1 course after the therapy. Remarkable effect was defined by reduction rate of VAS >80% after therapy, improvement by VAS reduction by 20% and 80%, and no effect by VAS reduction by < 20%.MAIN OUTCOME MEASURES: VAS score of the patients in the twogroups before and 1 course after therapy, and curative effect 1 treatment course after therapy.RESULTS: VAS of the patients in the acupuncture control group and combined therapy group was significantly decreased after 1 course of therapy in comparison with that before therapy (1.30±0.90 vs 6.57±1.21 for the former and 0.50±0.40 vs 6.64±1.13 for the latter, t=23.958 and 35.116, P < 0.01).Reduction rate of the score was significantly higher in combined therapy group than in the control group [(93.14±10.12)% vs (80.13±11.08)%,t=8.764, P < 0.01], and so was the total effective rate (remarkable effect rate and improvement rate, 93.6% vs 78.7%, χ2=4.644, P < 0.05 )].CONCLUSION: Fluid acupuncture with compound Danshen injection solution in combination with spectrum therapy can significantly relieve the pain caused by chronic soft tissue injury, with better effect than simple acupuncture therapy.

Journal of Clinical Medicine in Practice 2024;28(1):13-19
Objective To investigate the effects of long non-coding RNA (LncRNA) solute carrier organic anion transporter family member 4A1 (SLCO4A1-AS1) targeting microRNA-615-5p (miR-615-5p) in esophageal cancer cells on cell proliferation, apoptosis, and expression of inflammatory factors. Methods Real-time quantitative polymerase chain reaction (RT-qPCR) was used to analyze the expression of LncRNA SLCO4A1-AS1 and miR-615-5p in esophageal cancer tissues and cell lines. Eca109 cells were transfected with si-NC, si-LncRNA SLCO4A1-AS1, miR-NC, miR-615-5p mimic, pcDNA, pcDNA-LncRNA SLCO4A1-AS1, si-LncRNA SLCO4A1-AS1+anti-miR-NC, and si-LncRNA SLCO4A1-AS1+anti-miR-615-5p. Cell viability and apoptosis rate were measured by CCK-8 and flow cytometry, respectively; cell proliferation was determined by plate cloning assay; and levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in the culture medium were measured using an enzyme-linked immunosorbent assay (ELISA) kit. A dual luciferase reporter gene assay was used to determine the relationship between LncRNA SLCO4A1-AS1 and miR-615-5p. Results Expression of LncRNA SLCO4A1-AS1 was upregulated, and miR-615-5p expression was downregulated in esophageal cancer tissues and cell lines. After inhibiting LncRNA SLCO4A1-AS1 expression, cell viability, the number of cell clones, and levels of IL-6 and TNF-α in the culture medium decreased, while miR-615-5p expression and apoptosis rate increased (

Objective To investigate the expression of miR-451 and its clinical significance in gastric cancer. Meth?ods The miR-451 expression was detected in 92 samples of gastric cancer and 47 sapmles of normal stomach mucosa. The correlations of miR-451 expression with clinicopathologic characteristics, overall survival and disease-free survival were an?alyzed in patients with gastric cancer. Results The overexpression rate of miR-451 was 38.04%in gastric cancer, which was significantly lower than 76.60%in adjacent normal tissues (χ2=18.503,P<0.001). The overexpression rate of miR-451 was significantly lower inⅢ-Ⅳstages of gastric cancer than that inⅠ-Ⅱstages (27.3%vs 54.1%, P=0.009). The expres?sion of miR-451 was also lower in patients with lymph node metastasis than that in patients without lymph node metastasis (27.1%vs 57.6%, P=0.004). However, there were no significant differences in miR-451 expressions between different age, gender, histological grade and T stage groups (P>0.05). The overall survival rate was significantly higher in patients with high expression of miR-451 than that in patients with low expression of miR-451(69.2%vs 39.1%, P=0.003). Conclusion miR-451 is associated with the malignant transformation, progression, and prognosis of gastric cancer, and which can be used as a potential target of therapy and a biomarker of diagnosis and prognosis of gastric cancer in the future.
